1.	The volume of the water needed to dissolve `1 g` of `BaSO_(4) (K_(SP)=1.1xx10^(-10))` at `25^(@) C` is:A. `280 litre`B. `410 litre`C. `205 litre`D. None of these
Answer» Correct Answer - B Solubility of `BaSO_(4)=sqrt(K_(SP))=sqrt(1.1xx10^(-10))` `= 1.05xx10^(-5) M` `:.` Wt. of `BaSO_(4)=1.05xx10^(-5)xx233` `=244.37xx10^(-5)g//L` `:.` Volume of water needed to dissolve `1 g BaSO_(4)` is equal to `(1)/(244.37xx10^(-5))=410 L`
